When people are young and middle-aged, their liver is full of qi and blood, so their hair grows fast and shiny, but when they are old and weak, their hair turns white and withers, which is directly caused by the lack of nutrition provided by the spleen and stomach. Good hair has good health. The premature graying, yellowing and massive shedding of hair indicate that there is something wrong with the body, so we must attach great importance to it and take timely measures to prevent the disease from spreading in the body.
Chinese medicine says that the kidney stores essence, and its flowers are in the hair; The liver stores blood and sends it with blood; Deficiency of essence and blood and black hair are important symptoms of many diseases. Such as heart, liver, spleen, lung, stomach and kidney diseases, endocrine diseases, nervous system diseases, psychological diseases, blood and circulatory diseases, head skin diseases, etc. Will be reflected in the hair to varying degrees.
All the nutrients needed by hair and hair follicles are provided by blood in capillaries at the bottom of hair follicles. Once people have insufficient blood, their hair will not have enough nutrition, so there will be some problems such as dryness, yellowing, bifurcation, shedding and even white hair. Hair follicles are not getting enough nutrition. In one case, the ability to synthesize melanin is weakened and white hair appears. On the other hand, hair loss is rare.
